No. Reference (Part/Sec/Para/Page) QUESTION GOVERNMENT RESPONSE

001 Part 3/Section 1/Paragraph 4/Page 1 of 11 In order to keep runoff from flooding and running over the runway or taxiway, the stormwater drainage system must be developed in accordance with UFC 3- 201-01. To ensure positive drainage, the unpaved shouldering slope of the taxiway must be enhanced. In this instance, the installation of the storm drainage system will have an impact on the existing taxiway lighting systems that are now in place on the unpaved shoulder. Will the contractor be responsible of replacing the current lighting systems on the taxiway?

Given that a separate contract is underway for the paving of the taxiway shoulders.

The contractor will not be responsible for the replacement of the existing taxiway lighting systems unless the lighting systems are directly damaged by the contractor's operations. The contractor will be responsible for protecting existing lighting systems during construction activities and for restoring them to their original condition or better, unless otherwise directed by the Contracting Officer.

Installation of a storm drainage system is not a requirement.

Per RFP Part 3, Sec 1, para. 6: The project elements listed above must not damage the existing airfield utilities already in place.

Part 3, Sec 1, para 3, has been revised to read:

Stormwater management measures shall be designed per UFC 3- 201-01 to prevent stormwater from flooding and flowing over the runway and causing hydroplaning conditions. Correct localized drainage issues and improve pavement grades for positive drainage. To prevent pavement damage, the finished pavement grades and cross-slope shall be improved to accommodate a minimum flow rate of 0.8 cubic meters per second (or 28 cubic feet per second) within each internal area.

3.1 EXISTING SITE CONDITIONS

The project is located in Antonio Basa Air Base in Floridablanca, Pampanga. Coordinates: IVO

14°59'26.46"N, 120°29'52.24"E. The current conditions of taxiways Delta-Echo (TW D-E) and Charlie-

Echo (TW C-E) were observed to have weathering and raveling across its entirety and produce FOD. The pavement materials and approximate depths are indicated in Basa Air Base Runway As-Built Drawings

(RFP Part 6, A4).

Currently, a separate contract to construct taxiways shoulders is underway with estimated completion by

22 May 2025. Should the construction of shoulders begin within this period, contractor shall include it its plan to work concurrently with the other contractor.

Contractor shall minimize interruption to the on-going base operations. All other actions not involving interruption of services can be conducted during regular working hours. In the event work/project activities other than what is indicated in this project program is to occur simultaneously, contractor shall verify, coordinate and may be required to phase such work/project activities.

The asphalt surfaced taxiway sections displayed low, medium and high levels of weathering (see photos 1

-22 in Part 6, A-1) across its entirety.

The contractor shall obtain necessary local and national permits to include construction permits required by the local government and the Armed Forces of the Philippines (AFP). Because project site is located in an active aerodrome, work shall be in accordance with requirements of the Philippine Air Force (PAF).

1) Runway

Single runway with paved shoulders and unpaved taxiway shoulders. Construction of 7-meter paved taxiway shoulders are underway.

Width of runway = 44.2 m to 45 meters

Length of runway = 2800 meters

Overrun = 50 meters at each end Existing airfield edge lights and NAVAIDS; see Part 6 Attachment 3 for layout and approximate location.

2) Taxiways

The current condition of taxiways Delta-Echo (TW D-E) and Charlie-Echo (TW C-E) TW D-E was observed as being rutted with longitudinal cracks, unpaved shoulders, nearby adjacent overgrown vegetation, a lack of storm drain systems, and inoperable taxiway lighting systems which could cause significant issues during operations at the airfield. Existing taxiways have a full width of approximately 14.6 m [48 ft] to 15m [49 ft] with no paved shoulders. Paving of taxiways shoulders is underway via a separate contract. See Part 6 Attachment 10 for approximate locations and existing pavement surface conditions. As-built drawings for these taxiways are not available.

Width of taxiways = 14.6 m to 15 m

Length of TW D-E = approximately 1,140 m

Length of TW C-E = approximately 1,100 m Existing taxiway edge lights approximately 3 m [10 ft] from the taxiway edge; see Part 6

Attachment 3 for layout and approximate location.

The airfield's current stormwater runoff system is ineffective, causing water to flow over the runway and taxiway surfaces, leading to further deterioration. Additionally, the edge of the taxiway pavement and shoulders are breaking away, with block cracks and vegetation growing in the cracks.

Contractor shall provide minimum of 51mm (2”) new asphalt concrete overlay for Taxiways C, D and E in accordance with UFC 3-250-03, UFC 3-260-01, UFC 3-260-02, and UFGS Section 32

12 15.13, Asphalt Paving for Airfields.

3) Utilities

Contractor is allowed to connect to nearby existing primary power line, with coordination with the

Basa Air Base (BAB) Civil Engineer Staff Office (CESO). Note that contractor will have to provide their own step-down transformer and facilitate actual connection with supervision from the base engineer. It shall be contractor responsibility to pay for connection, metering, usage, disconnection and all other associated costs.

4) Temporary Construction Facilities and Controls

Workers' barracks are not allowed to be built in the vicinity of the project site, but the BAB shall allow the contractor use of selected existing structures outside the airfield but within the base to use as barracks and storage. Contractor shall be responsible for paying for use of facilities and consumption of base utilities.
